Hörspirale / Listening Spiral

Stations-ID: A003

Instructions:

Place your ear on one end of the spiral and speak into the other end slowly and clearly.

• Say short words loudly
• How much time do you think passes between speaking a word and hearing it?
• How long do you think the listening spiral is?

Small male frogs that are unable to find a mate due to their small, quiet sound sacs have a better chance at lower temperatures. Cold air conducts sound better, so the sound bubble sounds louder at low temperatures, and the males are more likely to be “heard.”
